VEHIOLE-WHEEL RIM.

Application filed may 28, 1911.

Yb all whom it may concern:

Be it known that l, JAMES H. lVAoEN- nonsr, a cit zen of the United States, residing in the city of Akron, county of Summit, and State of Gliio, have invented certain new and useful Improvements in Vehiclelvhecl llims, of which the following is a specification.

My invention relates to vehicle wheel rims of the type designed to carry pneumatic or other resilient tires and comprises im provemcnts in the structure of the rim proper to facilitate the application and removal of the resilient tire.

it also comprises improvements in. means for reinovably securing the rim proper, carthe tire. upon the wheel.

comprises certain improvements in c ills of structure, as will more fully appear hereafter.

In the'drawings forming a part of this specification I have illustrated certain preferred embodiments of my invention, and I will in this specification describe the same in detail in order that my invention may be fully understood. I do not, however, wish to limit my invention to the exact structures shown and described, as these structures are intended merely as illustrative of the many forms in which the principle of my invention may be embodied.

Referring to the drawings in detail and particularly to Figs. 1 to 12, inclusive, the numeral 1 designates a. tire-carrying rim adapted to carry a pneumaicgor other resilient tire 2, this rim preferably comprising a transversely split band or rim base 3 carrying annular, preferably endless, tire-retaining flanges 4. For holding the tire-retainin flanges upon the rim base the latter is preferably provided at each edge with. an upturned flange .3. In order to prevent circumferential movement or creeping of the flanges 4 upon the rim base, 1 preferably provide interlocking means such, for example, as that shown in Figs. 1, 2 and 5, or in Fig. 3. As shown in Figs. 1, 2 and 5, the rim base has formed in it, preferably by oilsetting the metal thereof, a pair of recesses or pockets 6, which receive projections 7 formed on the under-surfaces of the tire-re taining flanges. These recesses or pockets are preferably formed in the rim base adjacent to the perforations 8 therein, through which the valve-stem 9 of the tire is adapted to be passed. As will be understood, the

means for preventing the creeping of the flanges may be modified in various ways; for example, as shown in Fig. 3, instead of a pair of depressions 6, a single depression 10 extending entirely across the rim base may the rim, or 1 removal therefrom, I divide the rim base 3 traa1sversely, as indicated at i 12. The rim base is thus capable of being contracted diameter by having its ends lapped y each other, and may thus moved from the base 0 form of my invention shown in Figs. 1', 4, 5, 8, 10, 11 and 12, I have shown improved means for's'ecnring the ends of the rim base togntheigthese means constituting an imper-tent part of the present invention. In the embodiment shown in these fight-es, one end of the'rim base is providdd-wlth' a narrow projecting lip 13, offset from the body of the rim base toward the center ofthe Wheel and .adapted to en go lieneath'the abutting end of the rim. The other 1 end of the rim'baseis *gicovided with. similer lipilsfadspted-to-cngsge beneath, the end of therimbasecer 311g the'iip 13. ,These lips preferably m tend abeut halfway across the rim, cated in Figs. 2, 8

= endnlO.

When the rim is fitted with a tire and the parts thercoi are in ti iinormal operative positions, the tire-rething flanges are mounted upon the rim base, which is expanded into engagement" therewith, with its ends abutting, as shown in Fig. 8. The rim carrying the tire may then be socured upon the wheel in any desired manher. To detach a tire from the rim, the latter is first removed from the wheel and the tire deflated. The feet of the tire are then pressed together near the point Where the rim base is split and one of the flanges 4 moved in, as indicated in dotted lines in Fig; 8. The ends of the rim base may now be slid past each other laterally, as shown in the some figure, which will permit the narrow hols-3 at one end of the rim base to be cleared by the opposite end of the rim base, thus allowing the latter to be depressed and telescoped by the end of the rim base carry ing the lip 13. The rim base may'now be contracted and freedfrom the flanges 4 and the tire. In assem ling the parts, the reverse procedure is llowed, that is, the collapsed rim base is p aced within the tire and the flanges 4 and expanded into the position shown in Fig. 8, ally by each other until brought into alinement, when one end will be supported by the hp 14 and the other end by the lip 13 The coiiperatjon of the two lips 13 and 14 with the opposite ends of the rim base prevent either end of the latter from bein depressed, and the flanges 4 and the tire 'unequal width, as shown, hst themshould be quite narrow freed fro'm the retainin flanges 4 and 155 the tire. In the -on one end of the rim tendency I do not, howeyhp, fin

The lips 13 and need not be of in order to avoid the necessity for too great lateral movement of the ends of 'Lh In Figs. 13 and 14 I he fied form of tirecarry which w line we the split being at an angle to a radms, is indicated in Fig. H.

In Figs. 15 11113516 I have shown my in.

vention 1s embodid'in a, timepiece clenchcr rim 18,.having, instead of' the endless tireretaining ringsiorflangexd, integral tireretn'ining flanges 19. The -entire rim, in cluding the flangeshis 'cut'transverselralong a diagom'il line 29, the'pl'ene of the cut'being oblique to a radius, as -indicated in Fig. 16. A plate 21 is secured toftheunder-surface--of one end efil s rim and projects slightly soas to siphon the other end of the rim when the ends are brought into nlinement. The inclination of, the cut 20 prevents the depression of the end of the rim carrying the plate 21, as in the form of my 'entionshown in Figsf.13 and 14. As

lbs obvious, instead of forming thin at least one of to the under-surfers 1 cut on such an incline,'each end of the rim may be provided with a plate corresponding to the plate 21 extending part way across the rim; or integral lips, similar to the lips 13 and 14 shown in Figs. 8 and 10, may be rovided upon the opposite ends of the rim.

he heads of the tire will. be pressed firmly within the clenches 19 when the tire is inflated and will effectually prevent the accidental lateral displacement of the ends of the rim.

I have shown in Figs. 5, 6, 7 and 9 improved means for securing the tire-carrying rim upon the wheel. These means may advantageously be used with any of the forms of tire-carrying rim illustrated herein, but I do not wish to limit myself to the use of these securing means with my improved form of tire-carrying rim, as other means for accomplishing the same purpose may be substituted therefor. limit that part of my invention relating to the improved securing means to use. only with the improved form or forms of tirecarrying rim shown, as these improvements in securing means are of general application, Referring now particularly to the drawings, the felly 22 of the wheel is pro-' vided with a felly band 23 permanently 5e cured thereto by shrinking, or in any other suitable manner. This felly hand is provided at one edge with a raised flange having an inclined bearing surface 24. and at the other edge with a beveled bearing surface 25. The tire-carrying rim is provided with a pair of oppositely inclined internal bearing surfaces 26 and 27 which may be formed upon some integral part of the tirecarrying rim, though they are preferably formed upon a band 28 permanently secured to the under-surface of the rim base. The bearing surface 26 engages and is supported by the bearing surface 24 upon the felly band, while the bearing surface 27 is engaged and supported by the inclined surfaces 29 of a plurality of w ,dges 30. Any suitable number of wedges 30 may be em ployed, these wedges each having an internally threaded opening through the body portion thereof and screwing upon an ex ternally ant internally threaded nut or sleeve 31. l'gach sleeve 31 is provided with a head 32 at suitable form for engagement by a wrench or other means for rotating the same and screws upon the projecting threaded end 33 of a bolt 34 passing trans versely through the felly. These bolts are secured to the felly by means of nuts 35 and washers 36, or in any other suitable manner. These bolts are each preferably provided with beveled collars 37 of square or other angular shape, adapted to engage the walls of similarly shaped openings 38 m washers 39. The bolts thus secure the washers to the face ofthe flly, while'the wash- Neither do I wish to ers, being held from rotation upon the latter, as will be hereinafter described, pre vent the rotation of the bolts 31. The washers may be additionally secured to the folly and prevented from rotation thereon by means of screws passing through holes 40 therein. The washers are also provided at their outer edges with inwardly turned flanges 41 adapted to fit over the beveled surface 25 of the folly band, which engage ment thus further prevents the rotation of the washers. The outer surfaces of the flanges 41 preferably lie in the surface of a cylinder concentric with the axis of rotation of the wheel and serve to support the wedge portions of the members 30 and to guide the same into operative .osition between the folly band and rim. Fi ach washer 39 is also provided with a projecting flange 42 adapted to be engaged by a shoulder 13 formed upon each wedge member when the wedge members are rotated to operative position, as shown in full lines in Fig. 9, the lug or flange 42 being engaged by a second shoulder 44, also formed on each wedge member, when the wedge members are rotated to inoperative position, as shown in dotted lines in Fig. 9.

The operation of this locking device is as follows: Supposing the rim to be locked upon the wheel, the parts of the locking device being in position as shown in Fig. the not or sleeve 31 will be rotated in such a direction as to screw along the bolt portion 33 in a direction away from the felly. The external thread upon the nut or sleeve 31 is given a pitch opposite to that of the bolt portion 33, so that this rotation of the nut or sleeve 31 will. cause the wedge. member 30 to move along the sleeve 31 in the direction of the head 32 thereof. The wedge member 30 will thus have a combined movement equal to the sum of the pitch distances of the two threads for each revolution of the sleeve or nut. When the wedge member has been drawn out sufficiently so that its end. clears the washer 39. it will rotate with the nut or sleeve 31 in the direction indicated by the arrow in Fig. 9, into the position shown in dotted lines in that figure, where it will be stopped by the engagement of its shoulder 44 with the under-side of the lug 42. Vhen each of the wedges has been moved to-this position the rim is free to be removed fromv the wheel. To return the wedge member to operative position, it is simplnecessary to rotate the nut or sleeve. 31 in tlie opposite direction, which will first carry the wedge member back to upright position, where it will be stopped by the engagement of the shoulder 43 with the upper edge of the log 42. Further rotation of the nut or sleeve 31 will cause the wedgm moveinward, guided first by the engagement of the shoulder 43 with the lug 42, and then by the engagement of the under-surface of the Wedge member with the outer-surfaee of the flange 41 on the washer 39. The edging surface 29 0f the W dge mex'nhez' will finally engage with the 'surface 27 on the rim. the wedge n'iwfljwr l elug simported by the ()Htfiiffidlfi 0f the fikillg" 31 am? by the beveled sari on the fishy band.
